Connecting the Load

This chapter describes consideration to be given to the load, explains how to connect the load wires, and explains how to connect to the output terminals.

3.1 Reverse Polarity

When the current or voltage is set up as zero with the OUTPUT switched off case, a 0 V to 0.6 V reverse polarity voltage can arise. Because of this voltage, an opposite-directed 1 mA current flows to the load. Note that this load can reduce the product’s working life.

3.2 Load Considerations

Note that the output will become unstable if the following types of loads are connected.

Load with peaks and pulse-shaped current

The PMP indicates only mean values. Even when the indicated value is less than the preset current value, the peak values may actually exceed the preset current value. If this happens, the PMP is instantaneously put into constant-current operation mode, and the output voltage drops accordingly. For these types of loads, you must increase the preset current value or increase the current capacity.

Load that generates reverse current to the power supply

The PMP cannot absorb reverse current from the load. There- fore, if a regenerative load (such as an inverter, converter, or transformer) is connected, the output voltage increases and becomes unstable.

For these types of loads, connect a resistor RD as shown in Fig. 3-3 to bypass the reverse current. However, the amount of current to the load decreases by max. reverse current Irp.

Fig. 3-3 Remedy for regenerative load

• For resistor RD, select an appropriate resistor rated for the power (allowing sufficient margin).

• If a resistor with insufficient rated power for the circuit is used, resistor RD may burn out.

Load with accumulated energy

Connecting a load with accumulated energy, such as a battery, to the PMP may cause current to flow from the load to the internal circuit of the PMP. This current may damage the PMP or reduce the life of the battery. For this type of loads, connect a reverse-current-prevention diode (DRP) between the PMP and the load in series as shown in Fig. 3-4.

• To protect the load and the PMP, select DRP according to the following criteria.

Reverse voltage withstand capacity: At least twice the rated output voltage of the power supply.

Forward current capacity: Three to ten times the rated output current of the power supply.

A diode with small loss.• Be sure to take into account the heat generated by

DRP. DRP may burn out if heat dissipation is inade- quate.

3.3 Connecting the Load

This section describes the wire used to connect the PMP to the load, and the connection to the output terminal.

• Before connecting to the load, confirm that the POWER switch is turned on, and that the OUTPUT is turned off.

• Using a CONFIG setting, you can set the power-on output state. Check the output state before you connect the load. For details on the output state, see “Out- put state at power-on setup (“ON.PO”)” on page 4-34.

3.3.1 Load Cable

• To prevent the possibility of fire, use a load cable with sufficient current capacity with respect to the rated output current of the PMP.

• To prevent the possibility of electric shock, use a load cable with a higher voltage rating than the isolation voltage of the PMP. For the isolation voltage, see Chapter 7, “Speci- fications”.

Current capacity of the load cable

Load cables must be rated to carry the maximum rated output current of the PMP. If their current rating exceeds the maximum rated output current, the cable will remain intact even if the load is short-circuited.

When there is a long distance to the load, use as thick a line as possible, more than recommended.

Allowable current of the cable dependent on the maximum allowable temperature of the cable insulation

The cable temperature is determined by a current-caused resistance loss, ambient temperature, and thermal resistance to the outside. Table 3-1 shows the allowable capacity of current that can flow through a heat-resistant PVC wire (single wire) having a maximum allowable temperature of 60 ºC when the wire is stretched horizontally in the air at an ambient temperature of 30 ºC. If the condition is such that PVC wires with lower heat- resistant temperature are used, the ambient temperature exceeds 30 ºC, or the wires are bundled resulting in low heat radiation, the current capacity needs to be reduced.

Table 3-1 Nominal cross-sectional area of cables and allowable currents

Taking measures against noise

It is better to make heat radiation as great as possible to allow a larger current to flow, when wires having the same heat-resistant temperature are installed. For measures against noise in the

load cables, however, installing the + (pos.) and – (neg.) output lines side by side or bundling them together is more effective against unwanted noise. The Kikusui-recommended currents shown in Table 3-1 are allowable current that have been reduced in consideration of the potential bundling of load cables. Use these values as a guideline when installing load wires.

Limitations of the sensing function

Because wires have resistance, voltage drop in wires becomes greater as the wire becomes longer or the current becomes larger. This causes the voltage applied at the load end to be smaller. The PMP has a sensing function that compensates for this voltage drop, but compensation of up to approximately 0.3 V is available for a single line. If the voltage drop exceeds this level, wires having a greater sectional area should be used. When the voltage drop exceeds 0.6 V, internal circuits might break down.

As well, when using the sensing function, a negligible current will flow through the sensing line. For this reason, if there is a resistive component in the sensing line, it becomes a source of measurement error. Use a sensing wire with the lowest resistance as possible.

Withstanding voltage of the load wire

For load cables, use a cable with a rated voltage higher than the ground contact voltage of the PMP.

3.3.2 Connecting to the Output Terminal

Possible electric shock.• Be sure to turn off the POWER switch off before

connecting the output terminal. • When chassis ground terminal and COM termi-

nal are unconnected, install a binding post cover.

• If you are using the CH1, CH2, CH3, or CH4 terminal, be sure to attach the binding post cover.

• Use a crimping terminal to reliably connect the load cable to the output terminals.

• Each output is output to a COM terminal. The 3-output models have internal circuits with the outputs isolated between CH1 and CH2/CH3, and separated COM terminals. As well, the 4-output model has internal circuits with the outputs isolated between CH1/CH2 and CH3/CH4, and separated COM terminals. With both models, the allowable voltage gap between COM terminals is 30 V. Be careful when using the unit where the electric poten- tials differ.

1. Turn off the POWER switch.

2. Attach crimping terminals to the load cable and connect it to the output terminal.

3. Check the connection.

4-2 PMP

4.1 Turning On the Power

Turn the power on without the load connected.

• The CONFIG parameters can be set so that the output is automatically turned on when the POWER switch is turned on. When this function is enabled, the PMP powers up with the output turned on even if the output was off when the PMP was turned off the last time. There is a possibility that a load may break, if you connect a different load and turn the POWER and output on simultaneously.

POWER Switch-on

1. Check that the power cord is correctly connected.

2. Turn on the POWER switch on the (|) side.

Press the POWER switch on the (|) side and the instrument turns on. If there is an odd sound or odor, any abnormality, fire or fumes, pull the plug from the outlet.

3. Check the firmware version on the front panel display.

After displaying the version as shown in Fig. 4-1, the screen shows held-settings status (displays output values).

After purchase, when first turning on the POWER switch, the factory-shipped settings will come up. Apart from these, previous states may come up when turning on the POWER switch.

However, the tracking function settings being cancelled, these will show.

■ Inrush Current

When the power switch is turned on, the maximum inrush current of 120 A may flow. In particular, with a system using multiple models of the product, when the power switch is turned on at the same time, make sure that there is enough of a margin, taking into consideration the capacity of the distributor panel or the AC power line.

POWER Switch-off

pressing the POWER switch (O) side turns the PMP off.

The PMP saves the items below just before the POWER switch is turned off. These items are previous states may come up when turning on the POWER switch.

• Setting values of each output

• Setting state of each switch

If you immediately turn off the POWER switch after changing the settings, the last settings may not be saved. Take an interval of 2 seconds or more.

• Allow an interval of 5 seconds or more between power cycles. Any shorter interval poses the risk of shorting the working life of the input fuse and the POWER switch.

4.3 Basic Operation

First, output setting methods are explained. Then, methods for using constant voltage power supply and constant current power supply are explained.

4.3.1 Setting the Output

The PMP can select and set the setting digit when output voltage and output current are being selected.

1. Check that the display’s KEYLOCK LED on the display is extinguished.

When this KEYLOCK LED is lit, the output cannot be set.

2. Check that the rear panel J1 terminal base is open.

3. Check that the display OUTPUT LED on the display is not lit.

If the OUTPUT LED on the display is lit, turn off the OUTPUT switch. Also, if the OUTPUT switch is turned on, the output will vary depending on the settings.

Page 4-34

Using a CONFIG setting, you can set the power-on output state. Check the output state before you connect the load.

4. Press the SET switch to change to the setting display.

SET switch lights it. When the SET switch is lit, the panel display shows the setting. When it is not lit, the panel displays the actual output value.

• When the OUTPUT is turned on, the SET switch being lit means that the setting value is displayed and the outputs will differ.

• If the SET switch is lit when the output is on, you can change the output value while viewing the setting. Changing the setting changes the actual output value.

5. Press the channel selection switch that corresponds to the channel whose output value you want to set.

The selected channnel selection switch lights up.

See

4-6 PMP

6. To set the output voltage, press the VOLTAGE switch, and to set the output current, press the CURRENT switch.

With each press, the highlighted digit in the voltmeter or ammeter display is changed.

7. The highlighted digit can also be set with the rotary knob.

Hereafter, the digits are numbered from the side of the most significant digit (leftmost).

The most significant digit (leftmost) cannot be selected and set.

Page 4-35 to Page 4-37

Using CONFIG settings, you can set how the voltage and current settings behave when they are near the maximum or minimum limits and set how the digit that is one digit lower than the least-significant, displayed digit behaves (fine setting).

As an example, output setting methods are explained below, using PMP16-1QU with the CH3 (-16V, -1 A) output set to -5.2 V and -0.35 A.

1. Pressing the SET switch Setting display.

SET switch lights it.

2. Pressing the channel selection switches of CH3.

The selected channel selection switch of CH3 lights up.

3. Press the VOLTAGE switch and select digit 2 in the voltmeter display.

Digit 2 on the voltmeter is highlighted.

4. Turn the rotary knob right to set the value to “5”.

5. Press the VOLTAGE switch one more time and select digit 3 of the voltmeter display, and turn the rotary knob right to set the value to “2”.

The above voltage setting is finished. Next is the current setting.

6. Press the CURRENT switch and select digit 2 of the ammeter display.Digit 2 on the ammeter is highlighted.

7. Turn the rotary knob right to set the value “3”.

8. Press the CURRENT switch one more time and select digit 3 of the ammeter display, and turn the rotary knob right to set the value to “5”.

The current setting above is finished. Similar steps are performed for other output settings.

• If turning the rotary knob causes the set digit to go above “9”, or below “0”, the value of the digit that is higher by one step is changed.

• By enabling the fine voltage/current setting function during the CONFIG setting, it is possible to set the value of the digit that is by one digit lower than the least significant digit shown on the voltmeter/ammeter. You can set the digit when the least-significant digit is highlighted and is blinking. For details on the voltage and current fine settings, see “Voltage fine setup (“VO.FI”)” on page 4-36 and “Cur- rent fine setup (“CU.FI”)” on page 4-37.

4.3.2 Output Operation

The OUTPUT switch is a toggle switch. When the output is on, the OUTPUT indicator on the display illuminates; when the output is off, the OUTPUT indicator does not illuminate.

When the output is on, the present setting is output. If you change the setting while the output is on, the change is applied to the output.

Page 5-5

You can also turn the output on and off through external control.

Fig. 4-2 Examples of output on display

Output on/off when power is turned on

Page 4-34

By factory default, the output is off when the power is turned on. You can set the output state at power-on to on (ON.PO) in the CONFIG settings.

If you set the output state at power-on to on, check the voltage setting value and current setting value before you turn off the POWER switch.

Output on/off delay function

Page 4-25

You can set a delay time (in the range of 0.1 s to 99.9 s) that specifies how long it takes for the output to actually turn on or off after you press the OUTPUT switch. You can use this function when you want to turn the output on and off by specifying a time offset based on load characteristics.

4.4 Constant Voltage (CV) and Constant Current (CC) Power Supplies

The product has functions for constant voltage power supply to maintain a fixed/regularized output voltage, and for constant current power supply that maintain a fixed output current, even as the load changes. The state of operation for constant voltage supply is called “CV mode”, and for constant current supply, “CC mode”. These operating modes are determined by the following three values.

• Output voltage setting value (VS)• Output current setting value (IS)• Load resistance value (RL)

These operations are detailed in the following.

Fig. 4-3 Constant voltage operation and constant current operation

Fig. 4-3 illustrates the operating modes for the PMP. RL stands for the load resistance value, and RC stands for the resistance value calculated from the current and the voltage setting value (RC = VS/IS). The regulated power supply is designed as operating in CV mode when the operating point is in the range, and in CC mode when the operating point is in the range. The straight line (RL = RC) is a line between CV mode and CC mode. This line shows loads for which the output voltage and the setting voltage are equalized, or which the output current and the setting current are equalized. If load resistance RL is

greater than load resistance RC, the power supply operates in CV mode because the operating point is within the range. At this time, the current setting value IS becomes the current limit value.

When operating in CV mode, the output voltage is maintained at the voltage setting value. The output current is determined by the relation I=VS/RL, and is reduced to a value below the current limit value IS. Note that the current of the setting value does not flow at this time.

For the loads to allow transient peak current flow, the current limit value must be set so that the peak current does not reach the limit value.

Conversely, if load resistance RC is greater than load resistance RL, the power supply operates in CC mode because the operating point is within the range. At this time, the voltage setting value IS becomes the voltage limit value.

When operating in CC mode, the output current is maintained at an established current value. The output voltage is determined by the relation V=IS × RL, and is reduced to a value below the current limit value VS. Note that the voltage of the setting value is not applied at this time.

For the loads in which transitory surge voltage arises, the voltage limit value must be set so that the surge voltage does not reach the voltage limit value.

■ Crossover point

The unit switches between CV mode and CC mode automatically depending on the load. The points where the transition occurs are called crossover points.

For example, in CV mode, when the load changes and the output current reaches the current limit value, there is an automatic transition to CC mode in order to protect the load. Similarly, in CC mode, when the output voltage reaches the voltage limit value, there is an automatic transition to CV mode.

Example of CV/CC mode operation

The following example assumes a power supply at rated output voltage 100 V and rated output current 10 A.

Connect an 8Ω load resistance (RL) to the power supply’s output terminal and set the output voltage to 30 V and the output current to 5 A. In this case, because Rc=30 V/5 A, and 8Ω > 6Ω (RL > Rc), CV mode is activated. When the voltage rises while still in CV mode, because Vs=5 A × 8Ω = 40 (Vs=IS × RL), the voltage can go up to 40 V. When the voltage goes higher than this value, the crossover point is reached, and there is an automatic transition to CC mode. To maintain CV mode, raise the current limit value.

Next, connect a 5 Ω load resistor (RL) to the power supply’s output terminal, and establish a 30 V output voltage and a 5 A output current. In this case, CC mode is activated because RC= 30V/5 A = 6 Ω and 5 Ω < 6 Ω (RL< RC). When the current rises while still in CC mode, it is possible that the current value will rise to a level higher than IS=VS/RL up to IS=30V/5 Ω=6A. When the current goes higher, it reaches the crossover point, and there is an automatic transition to CV mode. To maintain CC mode, raise the voltage limit value.

4.4.1 Using the Unit as a Constant Voltage (CV) or Constant Current (CC) Power Supply

When you use the unit as a constant voltage power supply, the current setting value becomes the current limit value used to make current flow to the load.

When you use the unit as a constant current power supply, the voltage setting value becomes the voltage limit value that can be applied to the load.

When the voltage or current value reaches the set limit value, the active mode is automatically shifted. In accordance with the active mode, the lighting of the CV LED or CC LED over the channel selection switch of the applicable constant voltage/current is shifted, which indicates to shift the active mode between them.

The step for using the unit as a constant voltage (CV) or constant current (CC) power supply are explained below.

1. Check that the OUTPUT is turned off when the POWER switch is turned on.

When the OUTPUT LED on the display is lit, pressing the OUT- PUT switch turns the OUTPUT off.

Releasing the alarm (OHP)

In order to cancel the overheat protection (OHP) state, turn off the POWER switch once, and after removing the cause, turn on the POWER switch again.

If the operative cause of the overheat protection (OHP) is still present, there may be yet another OHP. Turn on the POWER switch after the internal temperature has dropped sufficiently.

If you cannot clear the alarm even when all of the causes of the alarm occurrence are eliminated, the PMP may have malfunc- tioned. If this happens, stop using the PMP and contact your Kikusui agent or distributor.

4.5.2 Overvoltage Protection (OVP) Function

The over-voltage protection (OVP) function protects the load from unexpected and excessive voltages. Over-voltage protection (OVP) is activated under the following situations.

• When an output caused by an internal control circuit failure results in an unregulated high voltage.

• When an abnormal external voltage is applied to an output terminal.

Activate over-voltage protection (OVP) operates at voltages that are 110% to 130% of each output’s rated voltage. This voltage depends on the internal circuitry of the product. It cannot be changed.

4.7 Tracking Function (TRACKING)

The tracking function varies the values of multiple specified channels by the absolute amount of change in the reference channel or in proportion (%) to the amount of change in the reference channel.

If performed within an active area, it can be varied from 0 V (or 0 A) to the rated voltage (or the rated current).

There are the following two kinds of tracking functions for PMP series.

It is possible to freely set the channel selection that performs a tracking operation, and the channel that will be the reference (only Tracking function 1).

Turning off the POWER switch, clears the settings of the tracking function set. When the PMP is turned on the next time, the unit is started up with the settings of the tracking function can- celed.

Tracking function 1 (absolute value variation)

This function varies the output of specified channels by the absolute amount of change in the selected reference channel. The voltage and current values of each channel that are in effect when tracking function 1 is activated become base values, and the voltage and current are varied from these values.

When you change the reference channel voltage or current and the output of a specified channel reaches the maximum settable output or 0 V (or 0 A), the output no longer changes. Even in this condition, the PMP keeps track of the changes in the reference channel so that when the reference channel output is returned to its original value, the tracking channel output also returns to its original value.

Tracking function 1

Function that uses an absolute value that is the same as the variation in the output voltage value (or the output current value) in a reference channel to vary the output voltage value (or the output current value) in other channels.

Tracking function 2

Function that changes the output voltage (or output current) of specified channels in proportion (%) to the specified output voltage (or current) reference.

4-18 PMP

Example) When tracking function 1 is activated with CH1 and CH2 of PMP16-1QU:

Set CH1 = 10.00 V, CH2 = 3.00 V, and assign CH1 as the reference channel. When CH1 is set as the reference channel, its settings are shown on the display.

Example 1) [CH1] [CH2]

10.00 V 3.00 VReference voltageSet TRACKING function 1.

Increase CH1 by 4 V.

14.00 V 6.18 VCH2 increase stops at the maximum voltage, but its variation result, which is 3 V + 4 V = 7 V, is saved.

Decrease CH1 by 0.5 V.

13.50 V 6.18 VCH2 becomes 7 V - 0.5 V = 6.5 V internally, but its actual voltage remains at 6.18 V.


13.50 V 6.00 V CH2 becomes 6.5 V - 0.5 V = 6.0 V.

Decrease CH1 by 3 V.

10.00 V 3.00 V CH2 returns to the original voltage.

Example 2) [CH1] [CH2]

10.00 V 3.00 VReference voltageSet TRACKING function 1.

Increase CH1 by 4 V.

14.00 V 6.18 VCH2 increase stops at the maximum voltage, but its variation result, which is 3 V + 4 V = 7 V, is saved.

Channel selection switch is pressed to set the reference channel to CH2.

14.00 V 6.18 VThe reference level changes to the voltage as shown on the left, and the past variation is cleared.


11.00 V 3.18 V CH1 becomes 14.00 V - 3.00 V = 11.00 V.


10.82 V 3.00 VCH2 returns to the original reference voltage, but CH1 becomes 10.82 V and does not return to the original reference voltage.

Tracking function 2 (variation ratio)

This function varies the output of specified channels in proportion (%) to the changes in the reference channel. The voltage and current values of each channel that are in effect when tracking function 2 is activated become base values (that correspond to 100 %), and the voltage and current are varied from these values.

The variable range is from 0.0 % to 200.0 %.

When you change the ratio and the output of a specified channel reaches the maximum settable output or 0 V (or 0 A), the output no longer changes. Even in this condition, the PMP keeps track of the changes in the tracking channel so that when the reference channel output is returned to 100 %, the tracking channel output also returns to its original value.

Example) Examples of the voltage variation of CH3 and CH4 of PMP16-1QU is shown in Fig. 4-8.

When the rotary knob is turned during tracking operation, the output levels vary in the same ratio as the set ± output ratio (b/a) as shown in Fig. 4-8. In other words, the following proportional expression is applied in this case.

b/a = d/c

For tracking function 1, if the function is turned off on the reference channel, tracking does not take place on any channels (even if the tracking function on the tracking channels is turned on). To use tracking function 1, be sure to turn on the function on the reference channel.

Setting resolution in tracking operation

When setting the resolution for the tracking operation, to be selected using the VOLTAGE or CURRENT switch.

• The output resolution of each channel is equal to the least-significant, displayed digit. If the reference-channel resolution is less than the tracking-channel resolution, the output on the tracking channel may not change when you turn the rotary knob. If this happens, keep turning the rotary knob until the tracking channel output or display changes.

About tracking function 1

• During tracking operation, you can press a channel selection switch to display the corresponding channel setting. When you do this, the amount of change in the tracking operation is cleared. The settings of each channel at this point become base values, and the reference channel switches to the selected channel.

• During tracking operation, if you change the reference channel when the tracking channels have reached their rated output, 0 V, or 0 A, the amount of change is also cleared. In this case, the rated output, 0 V, or 0 A becomes the base value.

• Be aware of these facts when you press the channel selection switch during tracking operation.

• If a memory switch is pressed during tracking function operation, the settings stored in the memory become the reference values.

• Even if the channel that is currently displayed has its tracking function turned off, channels that have the tracking function turned on perform tracking operation. As with the channels that have their tracking function turned on, the percentage that is displayed for a channel that has its tracking function turned off also changes, but the actual setting does not change.

• If a memory switch is pressed during tracking function operation, the settings stored in the memory become the reference values.

4.8 Delay Function

The actually delay time period between the press of the OUT- PUT switch and the actual switching of the outputs to ON (ON DELAY) or OFF (OFF DELAY) can be set. You can set sepa- rate delay times for ON and OFF.

The available setting range of DELAY TIME is between 0.1 to 99.9 seconds.

The following timing chart of ourput on delay and output off delay shows the concepts of the delay function.

Fig. 4-12 Timing chart of delay function

The actual rise time with output on and actual fall time with output off vary depending on the output and the load condition. Note that the timing chart above ignores the rise and fall time.

• Due to the internal processing time, the time until the output is turned on or off after the OUTPUT switch is pressed contains an error of a few tens of milliseconds even when the delay time is set to 0 second to delay time.

Recalling settings

• When memory settings are recalled while the output on is turned on, the recalled setting values are output. Be careful not to recall a wrong memory number to avoid applying an unexpectedly high power to the load. In the memory banks that you would not use, it is recommended to store the voltage and current values that would not damage the load.

Press the memory switch that stores the setting values. The settings in the selected memory will be recalled.

To view the stored settings, press a memory switch while the OUTPUT switch is off. The settings stored in the specified memory are displayed. If you want to use the settings immediately, turn the OUTPUT switch on.

When memory settings are recalled while the OUTPUT switch is turned on, the rise time of each output may be deviated by about 1.5 second.

• You cannot recall settings while the delay function is in operation.

4.10 Series Connection (only for PMP16-1QU)

• The series operation is possible only with PMP16- 1QU. It is not available with PMP18-3TR/PMP25- 2TR.

• It is not permitted to perform the series operation by combining the outputs of more than one unit. Other- wise, flowing a current into the internal circuitry may cause a failure.

The output voltages of two channels can be combined and mag- nified by connecting the load to their + (positive) and – (negative) output terminals.

4.13 Remote Sensing Function

The remote sensing function is used to reduce the influence of voltage drops due to the load cable resistance and stabilize the output voltage across the load.

The remote sensing function of the PMP can compensate up to approximately 0.3 V for a single line. Select a load cable with sufficient current capacity so that the voltage drop in the load cable does not exceed the compensation voltage.

If the voltage drops by more than 0.6 V, the internal circuitry may be destroyed.

To perform remote sensing, an electrolytic capacitor may be required at the sensing point (load terminal).

• With the factory setting, the PMP has been calibrated by connecting sensing wires to the output terminals. When calibrating the PMP, be sure to connect wires to the sensing and output terminals and execute calibration on the load side. See section 6.1 “Calibration” for details.

• To use the remote sensing function, it is required to turn it on in the CONFIG setting. If the remote sensing function is not turned on, an error of about 30 mV may result.

Remote Sensing Connection Procedure

Electric shock or damage to the internal circuitry may result.• Never connect wires to the sensing terminals while

the POWER switch is turned on.• The rated voltages of the wires to the sensing

terminals should be equal to or larger than the isolation voltage of the PMP. The isolation volt-age of the PMP is ±250 Vmax.

A small amount of current (max. 10 mA) flows through the sensing wires during the remote sensing operation. To prevent

WARNING

4-40 PMP

an error that may occur due to the resistance component of the sensing wires, use wires with as low resistance as possible.

When you are not using the sensing function, be sure to remove the sensing wires.

■ Electrolytic capacitor required

Capascitance 0.1 µF to several hundred µF

Withstand voltage: Greater than or equal to 150 % of the rated output voltage of the PMP

The channels to which the remote sensing is set are indicated with “1” on the ammeter display, and those to which the remote sensing is not set are indicated with “0”. The procedure to configure the channels is the same as that for performing tracking operation.

6. Confirm the connection of the sensing terminals.

Be sure to connect the sensing wires securely by referring to the checklist in Table 4-7.

■ If you are inserting a mechanical switch between the PMP and the load

If you want to turn the signals on and off using a mechanical switch that is inserted between the PMP and the load, be sure to include the sensing wires in the switch as shown in Fig. 4-22 and turn on and off the load wire and the sensing wires simultaneously. Be sure to turn off the OUTPUT or POWER switch before turning on/off the mechanical switch.

s

Is connection OK? Be sure to connect the sensing wires firmly. If a sensing wire is disconnected, the output voltage at the load end goes unstable and the load may be subjected to an exces-sive voltage.Also take care of the polarity of connection to prevent mal-function of the product.

Is a mechanical switch in use?

When turning the power supply to the load on/off using a mechanical switch, also insert a mechanical switch between the sensing wires to maintain the status of the load and sensing wires identical.

Is the product being used near the rated output voltage?

The outputs from the PMP are guaranteed only up to the rated voltage. If the voltage drops till the load end is too large and the voltage at the output end exceeds the rated voltage, stable voltage cannot be supplied to the load end and malfunction of the PMP may also result.In this case, replace the load wire with a wire with a larger cross-sectional area so that the voltage at the output end does not exceed the rated voltage.

Is induction prevented? Use twisted pair or shielded wires as the sensing wires, and be sure to connect the shield to the COM terminal. If a shielded area is exposed, protect it using an insulation tube having a higher withstanding voltage than the isolation volt-age of the PMP.

Is the withstanding voltage of the electrolytic capacitor enough?

Use an electrolytic capacitor with a withstanding voltage of 150% or more of the rated voltage of the PMP.

Aren’t the wire lengths too long?

When the length of the wire to the load is longer than 1 meter, oscillation may occur due to the inductance or capacitance of the wire. In this case, insert capacitors (with a rated voltage of some hundreds of µF) between the +S sensing terminal and the + output and between the –S sensing terminal and the – terminal. When connecting the capacitors, take care of their polarity so that the + (positive) polarity of the capacitor between +S and + comes on the + terminal side and that the + (positive) polarity side of the capacitor between –S and – come on the –S terminal side.

Are the countermeasures against pulsed load current sufficient?

If the load current changes suddenly into a pulse, the out-put voltage may be increased due to the inductance of the wire. To prevent this, use a sufficiently thick wire and use a capacitor with large capacitance on the load end.

Adjustment Procedures

The following four items can be adjusted for each output.

• Output voltage, offset

• Output voltage, full-scale

• Output current, offset

• Output current, full-scale

The adjustment can be started with any output. It is possible to adjust only the output voltage or output current, but both the offset and full-scale values should always be adjusted.

• In the CAL mode, the PMP outputs a voltage or a current for use in the offset and full-scale adjustments. However, the output value is not identical to the value used in the last performed adjustments. It is about 10% of the rated output in the offset adjustment and near the rated output in the full-scale adjustment.

Voltage adjustment procedure

• Be sure to connect wires to the output and sensing terminals before starting the voltage adjustments. If the sensing terminals are left unconnected, the output voltage may be deviated by some tens of milli- volts due to the effects of the internal circuitry and the load may be subjected to an excessive voltage. For details on the connection, see “Remote Sensing Connection Procedure” on page Page 4-39

*1. The voltage setting accuracy cannot be guaranteed when the difference between the remote sensing terminal voltage (voltage on the load end) and the output terminal voltage exceeds the compensating voltage. A small amount of current (max. 10 mA) flows through the sensing wires during the remote sensing operation. To prevent an error that may occur due to the resistance component of the sensing wires, use wires with as low resistance as possible. If the difference between the remote sensing terminal (voltage on the load end) and the output voltage exceeds 0.6 V, the internal circuitry may be damaged.

*2. The variation of the TRACK 1 function is possible within the range of the voltage (or current) output values of the reference channel. The variation of the TRACK 2 function follows the ratio of the output of the reference channel with respect to the output value at the start of tracking. The variation stops when the reference output value or interlocked output value exceeds the available value range.
